Francisco, Cal. Double- Acting Reversible 

 Gang Plows. Oct. 7, 1879. Filed Apr. 

 29, 1879. 



Claim. 1. The plow-beams C, crossing each 

 other diagonally within the frame A, and hav- 

 ing secured to them the oppositely placed gangs 

 of plows B, with an operating mechanism where- 

 by one gang may be elevated and the other 

 depressed, substantially as herein described. 



2. The plow-beams C, crossing each other 

 diagonally and carrying the plows B, one of 

 said beams having the arch or yoke E, where- 

 by one beam may be raised and the other de- 

 pressed simultaneously, substantially as herein 

 described. 



3. The plow-beams C, crossing each other 

 diagonally and carrying the plows B, as shown 

 in combination with the frame A, and the 

 guides D, substantially as and for the purpose 

 herein described. 



4. The plow-beams C, crossing each other 

 diagonally and having their ends fitted to move 

 in the guides D, in combination with the lever 

 F and G or an equivalent device, whereby the 

 beams may be moved in opposite directions 

 simultaneously, substantially as herein des- 

 cribed. 



5. In a gang plow, plow-beams crossing each 

 other diagonally, each beam carrying plows set 

 in a direction opposite to those on the other 

 beam, in combination with a frame in which 

 the said beams are supported and are vertically 

 adjustable, as set forth.

The side of the implement along which the 

 spades are arranged is supported upon legs, to 

 which is imparted by eccentrics a slight up-and 

 down and rocking movement which causes 

 them to propel the machine and simultaneously 

 operate the digging spades or forks. The ful- 

 crums of the legs, may be changed to regulate 

 their forward and backward (rocking) move- 

 ment. 



Claim. 1. The combined arrangement of 

 digging machine, consisting of a steam boiler 

 and engine, propelling legs G, ranged along 

 one side of the machine, movable rod H, for 

 varying the position of the fulcrums of these 

 legs and a series of digging forks worked to- 

 gether with the legs, substantially as described. 



2. The combined arrangement of supporting 

 and propelling legs G, with movable fulcrums 

 I' and rod H, for varying the positions of the 

 fulcrums, substantially as described, for support- 

 ing and propelling agricultural implements. 



3. The combined arrangement of supporting 



and propelling legs G, and digging spades or 

 forks working therewith, substantially as des- 

 cribed.

ronza, Ark. Steam Plows. Apr. 27, 1880. 



Filed Mar. 16, 1880. 



Claim. 1. The steam rotary plowing ma- 

 chine consisting of the frame A the driving and 

 gear wheels, whereby the plow cylinder is ro- 

 rotated the means for operating the levers E E 

 which sustain the plow cylinder consisting of 

 the transverse shafts R and b with their bevel 

 gears the side shafts H H, the pinions F' F', 

 and segments F F, all combined substantially 

 as and for the purpose described. 



2. The teeth or plow points bent baakward 

 from the centers, and having their points hook- 

 ed, substantially as shown, and for the purpose 

 described. 



3. The levers E E, pivoted on the shaft C, 

 having at their ends segment racks F, in combi- 

 nation with the cylinder P and pinion F' as 

 shown and described. 



4. The combination of the shafts R H H b 

 with their connecting beveled gears, the pinions 

 F' F', and segment racks F F, guide plates L 

 L, and cylinder P, substantially as and for the 

 purpose described.

The plow cylinder is composed of rings with 

 concave and convex sides, which fit into each 

 other and are clamped together and to the 

 centers or frame by screw rods. The teeth 

 are inserted in dovetail sockets capable of being 

 removed without taking the rings apart. 



Claim. 1. In steam-plows, a rotary plow 

 cylinder composed of rings having concavo 

 convex cross-sections, substantially as and for 

 the purpose described. 



2. The rings of the plow-cylinder, in com- 

 bination with the cutting points or teeth inser- 

 ted in a dovetailed socket and secured by dove- 

 tailed or conical headed screws inserted from 

 above substantially as and for the purpose des- 

 cribed. 



3. The combination of the series of concavo 

 convex rings// having eyes s the centers L" 

 and longitudinal screw bolts / with the shaft 

 K\ substantially as and for the purpose des- 

 cribed.

Claim. 1. The combination of the shaft C, 

 clutches B B, shaft nf shaft T, clutch gears s s 

 and traction wheels S S, substantially as des- 

 cribed. 



2. The combination of a traction engine, 

 carrying upon it a frame placed transversely to 

 the direction of the engine whose length is as 

 great as any one furrow plowed by the plows 

 driven by the engine, the frame being provided 

 on its lower side with ways whose ends are
